What is Vanguard?

Vanguard is the anti-cheat software for the Valorant game. That Riot software comes installed with the game to prevent players from cheating in Valorant.

Players have complained Vanguard blocks legitimate apps even when they’re not playing the game. When it blocks something, a Riot Vanguard notification appears above the Windows system tray area.

Does Valorant work in Windows 11?

Yes, Valorant is compatible with Windows 11. However, its Vanguard anti-cheat software enforces the same TPM 2.0 security system requirement as Windows 11.

That’s why some players have needed to fix the Van9001 error. However, the Van9001 error message makes it clear enough what needs to be enabled for Vanguard in Windows 11.
